Yeah, in both my '08 4.8i and the new Range Rover, incoming calls are automatically sent to the speakers in the car, right away. Like several have mentioned, you either have to turn off your Bluetooth setting (or if you are lucky to have an iPhone, you just switch audio sources from BMW/Land Rover to iPhone). It's easy, quick and smooth. I'm afraid, you are not going to be able to "undo" the upgrade, as it seems to be doing what it is supposed to do. Yeah, it is horrible when a call comes in, you have people in the car...and the call is private. Can you imagine how horrible, if you're in the car with your wife/husband...and your girlfriend/boyfriend calls. Akward!!!
